The graph given below shows the relationship between the extent of adsorption $(x / m)$ and pressure at different temperatures. The correct order of temperatures for curves $i$,$ii$,and $iii$ is:

Assuming Langmuir monolayer adsorption,the volume of nitrogen gas adsorbed on a sample of silica gel at $STP$ is $1.30 \, cm^3 \, g^{-1}$. The area occupied by a nitrogen molecule is $0.16 \, nm^2$. The surface area of silica gel per gram is ......... $m^2 \, g^{-1}$.

What is the value of the intercept on the $y$-axis when $\log \frac{x}{m}$ is plotted against $\log P$ in the Freundlich isotherm?

Which forms multimolecular layers during adsorption?

The adsorption of hydrogen by metals is called

The validity of the Freundlich isotherm can be verified by plotting:
